The ETL Systems CPL20L1P-4310 is a 20 dB L-band proximity coupler designed for RF signal monitoring in satellite, telecom, and test environments. It operates across the 850–2150 MHz frequency range and is particularly suited for applications requiring complete isolation of DC and 10 MHz signals.
Key Features:
- All RF ports are DC & 10MHz blocked.
- 20dB Coupling.
Available with RF connector options: 50 Ω SMA, 50 Ω N-Type, 50 Ω BNC, 75 Ω BNC and 75 Ω F-Type.
